CRCA
steel strips D.D grade 2.0 mm thick for header pipes in 75 mm or 90 mm
diameter as per customer requirement. Larger headers of 100 NB and 150
NB are also available as per customer requirements

Accessories
such as m.s square / round flanges, air vent, drain plug, lifting
hooks, bracing straps are standard but can be supplied as per customer
specific requirements.

Internal Surface Preparation

The
internal surface of the Radiators are washed and cleaned to avoid
transformer oil contamination with oil for transformers according to
ISO 4406 and coated (flush coating) with varnish. Internal surface
painting can also be arranged as per specific purchaser requirements.

External Surface Preparation

Our
standard products are de-greased prior to painting with two coats of
zinc chromate red oxide primer to prevent corrosion. Finished painting
is done by enamel / epoxy paint or as per customer specification. Sand
/ quartz / grit blasting as per customer requirement. We have a surface
treatment section equipped with steel shot blasting machine and
painting system.

Tests

All
Radiators are pressure tested individually for leak proofness, under
water at an air pressure of 200 kPa (2kg/ cm2) for 30 minutes.
(Standard water immersing test). Compliance is checked by immersing the
Radiators in a water filled tank. Randomly selected Radiators from all
consignments goes through hot oil test. (the Radiators are filled with
transformer oil at a temperature of 600 C and kept at a pressure of
200 kPa ( 2.0394 kgf/ cm2) for 3 Hours to ensure no oil leaks.

Our
Quality Control Division carries out one final check for radiator
cleanness, foreign bodies and other contamination. The Radiators passed
trough a stringent checking system developed by our qualified engineers
and technicians.

Flanges
are covered to prevent the ingress of contamination during
transportation or storage. We take all possible measures to avoid
mechanical damages to the Radiators.

With
our radiators, we try to serve our customers to reduce their costs
through savings on fluids due to our superior heat transfer, and the
reduction of number of elements per radiators per transformer (reducing
labor, handling, etc.)
